- 摘要：
PROBLEM TO BE SOLVED: To provide a method for producing particles, capable of producing the particles in simple and easy steps, and to provide, in a high yield, the particles having a homogeneous particle diameter and an excellent dispersibility in a liquid.
SOLUTION: The method for producing the particles comprises (1) a step of preparing an aqueous solution containing a polymer, (2) a step of introducing the aqueous solution as droplets into a solvent having a water solubility of 1 mass% or more and less than 50 mass% and (3) a step of preparing the particles containing the polymer in the solvent. In another embodiment, the method for producing the particles comprises (a) a step of preparing an aqueous solution containing a polymer and (b) a step of mixing the aqueous solution into a solvent having a water solubility of 1 mass% or more and less than 50 mass% so that the value calculated by the formula: (mass of water)/(total mass of the solvent and water)×100 does not exceed the solubility of water in the solvent, to prepare the particles containing the polymer.
